Hi Shelly,
My piece of advice: get or borrow the following book:
Toilet Training in Less Than a Day, by Nathan Azrin
http://www.amazon.com/Toilet-Training-Less-Than-Day/dp/06...
I used it and my son was #1-trained in half a day (had a total of 3 accidents after that,) and was asking for diaper when needed to do #2 before the end of the day. Three weeks later, on his own, started to go potty for that too. He still needed nitgh-time diapers for a couple of months after that, but I needed him potty-trained for pre-K first and foremost. I've recommended it to many friends, who all have had the same experience.
The book was written in 1973, and is in English English, so some of it is outdated or a little weird, but the method is painless (at least for the child, it's quite involved for the parent) and works wonders. I've always wondered why it's not something that everyone uses, because it's so much easier than the traditional methods...
Hope this helps,
K.
